The folks at Culture Making Blog have put together (above) a beautiful diagram of biblical cross-references:
This diagram arose from a collaboration between a Carnegie-Mellon Ph.D student and a Lutheran pastor to create a grand map of Biblical cross-references: "We wanted something that honored and revealed the complexity of the data at every level –- as one leans in, smaller details should become visible. This ultimately led us to the multi-colored arc diagram... The bar graph that runs along the bottom represents all of the chapters in the Bible. Books alternate in color between white and light gray. The length of each bar denotes the number of verses in the chapter. Each of the 63,779 cross references found in the Bible is depicted by a single arc - the color corresponds to the distance between the two chapters, creating a rainbow-like effect.
